Earlier quoted context omitted.
"the Paradise I am talking about, you don't die after entering it" Not every religion considers eternal life desirable. In some forms of Buddhism and Hinduism, for example, the ultimate goal is to leave the cycle of death and rebirth.. not in to paradise, but in to nothingness.
Such religions will also never be able to tell you what they are actually about. :)
Also, the ultimate reality in Buddhism, Hinduism, and (incidentally) mystic forms of Islam, is often described as being beyond words and even beyond conception, so there is a limited amount that could be said about it in ordinary language -- though that hasn't stopped people from trying.
In Buddhism one often hears the teachings described as the finger pointing towards the moon. Language may be inadequate to describe ultimate reality, but it can point to it.
